Dear Aspirant!! Congratulations on your score but I would like to inform you that they'll also consider your JEE Main score for admission as the mininum criteria is as follows: Candidates must have passed 10+2 or equivalent examination with at least 60% marks (for SC/ST candidates 55%) in aggregate of three subjects- Mathematics, Physics and any one subject out of Biology, Chemistry Technical Vocational subject and Biotechnology and then candidates will have to secure at least 20% aggregate marks (for SC/ST candidates 15%) in JEE Main 2018. Or candidates will have to obtain at least 15% aggregate marks (10% for SC/ST candidates) in JEE Main 2019. If you satisfy the above criteria you stand a chance to get into TIET depending on standard of other students.

Hope this helps.
